Coil Mattress vs Foam Mattress

Date: February 14, 2018

Author: admin

The different function of coil mattresses, also known as innerspring or spring mattresses, versus that of memory foam mattresses involves a difference in construction that leads to a difference in how the mattress interacts with the individual using the mattress

Support Method

Coil, or spring, mattresses rely on springs to support the sleeper. These springs push against the individual with equal force. This results in inadequate weight distribution and thus pressure points that produce such problems as aches, joint pain, and even poor blood circulation. Inner foam mattresses, however, in conforming to the sleeper’s body provide a more even weight distribution that reduces pressure points as described at the Searchwarp and Myessentia websites.

Temperature Sensitivity

Memory foam mattresses typically exhibit temperature sensitivity, allowing them to become more supple and to more fully adapt to the occupant’s body configuration as body heat warms the mattress as described at the Searchwarp and Myessentia websites. Coil mattresses do not exhibit such temperature sensitivity on their own; although some models involving a combination of an innerspring foundation with a memory foam topper do exhibit this characteristic.

Firmness

Both innerspring and memory foam mattresses have varying firmness depending on the precise brand and model, with innerspring mattresses deriving relative firmness by way of coil diameter: larger diameter coils provide a firmer-feeling mattress.

Considerations

Both types mattress have potential drawbacks for the purchaser to consider in making a choice among different mattresses. The drawbacks for memory foam mattresses include relative costliness, that some foams take longer than others to conform and recover to body contours, and in the case of models made with poor quality foam the potential for an unpleasant smell in new mattress models. For innerspring mattresses, the drawbacks include that they begin to sag within two years, that they do not distribute body weight evenly, that they have no provision for spinal alignment, and that warranties typically limit body impression to 1.5 inches which tends to occur within the first six months of use.
